RESUMO
PURPOSE: This study aimed to validate the previously reported association between delayed bladder repair and increased infection rates using the National Trauma Data Bank (NTDB). METHODS: Bladder injury patients with bladder repair in the NTDB from 2013 to 2015 were included. Propensity score matching (PSM) was used to compare mortality, infection rates, and hospital length of stay (LOS) between patients who underwent bladder repair within 24 h and those who underwent repair after 24 h. Linear regression and multivariate logistic regression analyses were also performed. RESULTS: A total of 1658 patients were included in the study. Patients who underwent bladder repair after 24 h had significantly higher infection rates (5.4% vs. 1.2%, p = 0.032) and longer hospital LOS (17.1 vs. 14.0 days, p = 0.032) compared to those who underwent repair within 24 h after a well-balanced 1:1 PSM (N = 166). Linear regression analysis showed a positive correlation between time to bladder repair and hospital LOS for patients who underwent repair after 24 h (B-value = 0.093, p = 0.034). Multivariate logistic regression analysis indicated that bladder repair after 24 h increased the risk of infection (odds = 3.162, p = 0.018). Subset analyses were performed on patients who underwent bladder repairs within 24 h and were used as a control group. These analyses showed that the time to bladder repair did not significantly worsen outcomes. CONCLUSIONS: Delayed bladder repair beyond 24 h increases the risk of infection and prolongs hospital stays. Timely diagnosis and surgical intervention remain crucial for minimizing complications in bladder injury patients.

PURPOSE: The effectiveness of open cardiopulmonary resuscitation (OCPR) remains controversial for trauma patients. In this current study, the role of OCPR in managing chest trauma patients is evaluated using nationwide real-world data. METHODS: From 2014 to 2015, the National Trauma Data Bank was retrospectively queried for chest trauma patients with out-of-hospital cardiac arrest status. The emergency department (ED) and overall survival of patients without signs of life were analyzed. Multivariate logistic regression (MLR) analysis was performed to evaluate independent factors of mortality for the target group. Furthermore, a subset group of patients who survived after the ED were studied, focusing on the duration of survival after leaving the ED. RESULTS: A total of 911 patients were enrolled in this study (OCPR vs. non-OCPR: 161 patients vs. 750 patients). The average overall mortality rate was 98.6% (N = 898). Among penetrating chest trauma patients, non-survivors in the ED had significantly higher proportions of gunshot injuries (83.9% vs. 69.7%, p = 0.001) and lower proportions of OCPR (20.7% vs. 44.4%, p < 0.001). MLR analysis showed that gunshot injuries and non-OCPR were significantly related to ED mortality in penetrating trauma patients without signs of life (odds ratio = 2.039, p = 0.006 and odds ratio = 2.900, p < 0.001, respectively). However, the overall survival rate of patients after ED survival (n = 99) was 9.9%, and only 21.2% (n = 21) of them survived more than 1 day after leaving the ED. CONCLUSION: OCPR could be considered in situations where appropriate indications exist. The survival benefit was observed in critically ill patients with penetrating chest trauma who show no signs of life. By enhancing ED survival, OCPR may also contribute to overall survival improvement.

BACKGROUND: The appropriate timing of surgical intervention for bladder injuries is not well-defined. The effect of time to surgery on the outcomes of patients with a bladder injury was assessed using data from the Trauma Quality Improvement Program. METHODS: Patients with dominant or isolated bladder injuries who underwent surgical repair from 2017 to 2019 were studied. Mortality, infection (surgical site infection or sepsis), acute kidney injury, overall length of stay, and length of stay after surgery were compared between patients who underwent bladder repair within and after 24 hours of arrival at the emergency department. The role of time to surgical repair in the outcomes of patients with a bladder injury was evaluated. RESULTS: A total of 1,507 patients with a mean time to bladder repair of 14.0 hours were studied. In total, 233 (15.5%) patients with a bladder injury underwent bladder repair more than 1 day after emergency department arrival. These patients had significantly more infections (5.6% vs 2.5%, P = .011), more acute kidney injuries (7.8% vs 1.8%, P < .001), and a longer length of stay after surgery (16.0 vs 12.3 days, P = .001) than patients who underwent bladder repair within 1 day. A time to bladder repair longer than 24 hours after emergency department arrival did not significantly affect mortality (P = .075) but significantly increased the risk of infection/acute kidney injury (odds = 1.823, P = .040). However, the infection/acute kidney injury risk did not increase with increasing time to surgery in patients who underwent bladder repair within 24 hours (P = .120). CONCLUSION: Patients with dominant or isolated bladder injuries may have a poor outcome (ie, increased infection rate, acute kidney injury, longer overall length of stay, and longer length of stay after bladder repair) if they undergo surgical repair more than 24 hours after arrival at the emergency department.

OBJECTIVES: The role of thoracic endovascular aortic replacement (TEVAR) in patients with concomitant blunt thoracic aortic injury (BTAI) and blunt abdomen trauma (BAT) was evaluated using nationwide real-world data. The risk of post-TEVAR abdominal haemorrhage was studied. METHODS: Patients with BTAI and BAT in the National Trauma Data Bank were retrospectively studied. Propensity score matching was used to evaluate the effect of TEVAR in delayed abdominal surgeries for haemostasis and the delayed need for blood transfusion. A multivariable logistic regression analysis was used to evaluate the independent risk factors for delayed intra-abdominal haemorrhage in these patients. RESULTS: A total of 928 concomitant BTAI and BAT patients were studied (TEVAR versus non-TEVAR, 206 vs 722). After a well-balanced propensity score matching analysis, patients who received TEVAR had significantly more delayed abdominal surgeries for haemostasis (7.7% vs 4.5%, standardized mean difference = 0.316) and delayed need for blood transfusion (11.6% vs 7.1%, standardized mean difference = 0.299) than those who did not. The multivariable logistic regression analysis showed that TEVAR increased the need for delayed abdominal surgeries (odds ratio = 2.026, P = 0.034). Among the patients who underwent TEVAR, the patients with delayed abdominal surgeries for haemostasis had a significantly higher proportion of severe abdominal injury (abdominal Abbreviated Injury Scale score of 4 or 5) than patients without delayed abdominal surgeries for haemostasis (31.6% vs 15.5%, P = 0.038). CONCLUSIONS: Patients with concomitant BTAI and BAT had a higher risk of intra-abdominal haemorrhage after TEVAR, especially patients with severe abdominal trauma.

PURPOSE: The impact of transarterial embolization (TAE) and nephrectomy on acute kidney injury (AKI) in blunt renal trauma patients remains unclear, and we used the National Trauma Data Bank (NTDB) to investigate this issue. METHODS: Adult patients from the NTDB between 2007 and 2015 who survived traumatic events with blunt injuries were eligible for inclusion. The exclusion criteria were those without outcome information, who required dialysis, or with chronic renal failure prior to the traumatic injury. Patients sustaining hepatic, splenic, or pelvic fractures or who had bilateral nephrectomy were also excluded. The patients were divided into three treatment groups, including conservative treatment, TAE, and nephrectomy. Two statistical models, logistic regression (LR) and inverse probability treatment weighting (IPTW), were used to clarify the AKI predictors. RESULTS: The study included 10,096 patients. There were 9697 (96.0%), 202 (2.0%) and 197 (2.0%) patients in the conservative, TAE and nephrectomy groups, respectively. Nephrectomy was a statistically significant predictor of AKI in blunt renal trauma patients in the standard LR (odds ratio [OR], 4.58; 95% confidence interval [CI] 1.92-10.38; p < 0.001) and IPTW (OR, 5.16; 95% CI 1.07-24.85; p = 0.023) models. In addition, TAE was not a risk factor for AKI in blunt renal trauma patients (p > 0.05 in all models). CONCLUSION: AKI is less likely affect patients with blunt renal trauma with TAE than those with nephrectomy. Nephrectomy is a risk factor for AKI in blunt renal trauma patients. TAE should be considered first when blunt renal trauma patients need a hemostatic procedure.

BACKGROUND: Open pelvic fractures are rare but complex injuries. Concomitant external and internal hemorrhage and wound infection-related sepsis result in a high mortality rate and treatment challenges. Here, we validated the World Society Emergency Society (WSES) classification system for pelvic injuries in open pelvic fractures, which are quite different from closed fractures, using the National Trauma Data Bank (NTDB). METHODS: Open pelvic fracture patients in the NTDB 2015 dataset were retrospectively queried. The mortality rates associated with WSES minor, moderate and severe injuries were compared. A multivariate logistic regression model (MLR) was used to evaluate independent factors of mortality. Patients with and without sepsis were compared. The performance of the WSES classification in the prediction of mortality was evaluated by determining the discrimination and calibration. RESULTS: A total of 830 open pelvic fracture patients were studied. The mortality rates of the mild, moderate and severe WSES classes were 3.5%, 11.2% and 23.8%, respectively (p < 0.001). The MLR analysis showed that the presence of sepsis was an independent factor of mortality (odds of mortality 9.740, p < 0.001). Compared with patients without sepsis, those with sepsis had significantly higher mortality rates in all WSES classes (minor: 40.0% vs. 3.1%, p < 0.001; moderate: 50.0% vs. 9.1%, p < 0.001; severe: 66.7% vs. 22.2%, p < 0.001). The receiver operating characteristic (ROC) curve showed an acceptable discrimination of the WSES classification alone for evaluating the mortality of open pelvic fracture patients [area under curve (AUC) = 0.717]. Improved discrimination with an increased AUC was observed using the WSES classification plus sepsis (AUC = 0.767). CONCLUSIONS: The WSES guidelines can be applied to evaluate patients with open pelvic fracture with accurate evaluation of outcomes. The presence of sepsis is recommended as a supplement to the WSES classification for open pelvic fractures.

BACKGROUND: After clinical evaluation in the emergency department (ED), facial burn patients are usually intubated to protect their airways. However, the possibility of unnecessary intubation or delayed intubation after admission exists. Objective criteria for the evaluation of inhalation injury and the need for airway protection in facial burn patients are needed. METHODS: Facial burn patients between January 2013 and May 2016 were reviewed. Patients who were and were not intubated in the ED were compared. All the intubated patients received routine bronchoscopy and laboratory tests to evaluate whether they had inhalation injuries. The patients with and without confirmed inhalation injuries were compared. Multivariate logistic regression analysis was used to identify the independent risk factors for inhalation injuries in the facial burn patients. The reasons for intubation in the patients without inhalation injuries were also investigated. RESULTS: During the study period, 121 patients were intubated in the ED among a total of 335 facial burn patients. Only 73 (60.3%) patients were later confirmed to have inhalation injuries on bronchoscopy. The comparison between the patients with and without inhalation injuries showed that shortness of breath (odds ratio = 3.376, p = 0.027) and high total body surface area (TBSA) (odds ratio = 1.038, p = 0.001) were independent risk factors for inhalation injury. Other physical signs (e.g., hoarseness, burned nostril hair, etc.), laboratory examinations and chest X-ray findings were not predictive of inhalation injury in facial burn patients. All the patients with a TBSA over 60% were intubated in the ED even if they did not have inhalation injuries. CONCLUSIONS: In the management of facial burn patients, positive signs on conventional physical examinations may not always be predictive of inhalation injury and the need for endotracheal tube intubation in the ED. More attention should be given to facial burn patients with shortness of breath and a high TBSA. Airway protection is needed in facial burn patients without inhalation injuries because of their associated injuries and treatments.

BACKGROUND: Civilians are often first-line responders in hemorrhage control; however, windlass tourniquets are not intuitive. Untrained users reading enclosed instructions failed in 38.2% of tourniquet applications. This prospective follow-up study replicated testing following Stop the Bleed (STB) training. MATERIALS AND METHODS: One and six months following STB, first-year medical students were randomly assigned a windlass tourniquet with enclosed instructions. Each was given one minute to read instructions and two minutes to apply the windlass tourniquet on the TraumaFX HEMO trainer. Demographics, time to read instructions and stop bleeding, blood loss, and simulation success were analyzed. RESULTS: 100 students received STB training. 31 and 34 students completed tourniquet testing at one month and six months, respectively. At both intervals, 38% of students were unable to control hemorrhage (P = 0.97). When compared to the pilot study without STB training (median 48 sec, IQR 33-60 sec), the time taken to read the instructions was shorter one month following STB (P <0.001), but there was no difference at 6 months (P = 0.1). Incorrect placement was noted for 19.4% and 23.5% of attempts at 1 and 6 months. Male participants were more successful in effective placement at one month (93.3% versus 31.3%, P = 0.004) and at six months (77.8% versus 43.8%, p = 0.04). CONCLUSIONS: Skills decay for tourniquet application was observed between 1 and 6 months following STB. Instruction review and STB produced the same hemorrhage control rates as reading enclosed instructions without prior training. Training efforts must continue; but an intuitive tourniquet relying less on mechanical advantage is needed.

PURPOSE: Whole-body computed tomography (WBCT) scans are frequently used for trauma patients, and sometimes, nontraumatic findings are observed. We aimed to investigate the characteristics of patients with nontraumatic findings on WBCT. METHODS: From 2013 to 2016, adult trauma patients who underwent WBCT were enrolled. The proportions of nontraumatic findings in different anatomical regions were studied. Nontraumatic findings were classified and evaluated as clinically important findings and findings that needed no further follow-up or treatment. The characteristics of the patients with nontraumatic findings were analyzed and compared with those of patients without nontraumatic findings. RESULTS: Two hundred seventeen patients were enrolled in this study during the 3-year study period, and 89 (41.0%) patients had nontraumatic findings. Nontraumatic findings were found more frequently in the abdomen (69.2%) than in the head/neck (17.3%) and chest regions (13.5%). In total, 31.3% of the findings needed further follow-up or treatment. Patients with nontraumatic findings that needed further management were significantly older than those without nontraumatic findings (57.3 vs. 38.9; P < .001), particularly those with abdominal nontraumatic findings (57.9 vs. 41.3; P < .001). A significantly higher proportion of women were observed in the group with head/neck nontraumatic findings that needed further management than in the group without nontraumatic findings (56.3% vs 24.9%; P = .015). CONCLUSIONS: Whole-body computed tomography could provide alternative benefits for nontraumatic findings. Whole-body computed tomography images should be read carefully for nontraumatic findings, particularly for elderly patients or the head/neck region of female patients. A comprehensive program for the follow-up of nontraumatic findings is needed.

PURPOSE: Geriatric trauma patients present physiological challenges to care providers. A nationwide analysis was performed to evaluate the roles of age alone versus age-associated comorbidities in the morbidity and mortality of elderly patients with blunt abdominal trauma (BAT). METHODS: Patients with BAT registered in the National Trauma Data Bank from 2013 to 2015 were analyzed using propensity score matching (PSM) to evaluate the mortality rate, complication rate, hospital length of stay (LOS), intensive care unit (ICU) LOS and ventilator days between young (age < 65) and elderly (age ≥ 65) patients. An adjusted multivariate logistic regression (MLR) model was also used to evaluate the effect of age itself and age-associated comorbidities on mortality. RESULTS: There were 41,880 patients with BAT during the study period. In elderly patients, the injury severity score (ISS) decreased with age, but the mortality rate increased inversely (from 5.0 to 13.5%). Under a similar condition and proportion of age-associated comorbidities after a well-batched PSM analysis, elderly patients had significantly higher mortality rates (8.0% vs. 1.9%, p < 0.001), higher complication rates (35.1% vs. 30.6%, p < 0.001), longer hospital LOS (8.9 vs. 8.1 days, p < 0.001), longer ICU LOS (3.7 vs. 2.7 days, p < 0.001) and more ventilator days (1.1 vs. 0.5 days, p < 0.001) than young patients. Furthermore, the MLR analysis showed that age itself served as an independent factor for mortality (odds ratio: 1.049, 95% CI 1.043-1.055, p < 0.001), but age-associated comorbidity was not. CONCLUSION: In patients with BAT, age itself appeared to have an independent and deleterious effect on mortality, but age-associated comorbidity did not.

BACKGROUND: In the management of patients with blunt abdominal trauma, delayed diagnosis and treatment of hollow viscus injury can occur. We assessed the effect of the time to surgery on the outcomes of blunt hollow viscus injury patients. METHODS: The National Trauma Data Bank was queried from 2012 to 2015 to identify patients with blunt hollow viscus injury for inclusion. Patients with unstable hemodynamics, concomitant intra-abdominal organ injuries, or other severe extra-abdominal injuries were excluded. Inverse probability of treatment weighting and multivariate logistic regression were used to evaluate the effect of the time to surgery on the outcomes. RESULTS: In total, 2,997 patients with blunt hollow viscus injury were studied; the mean time to abdominal surgery was 6.7 hours. Twenty-two hours was selected as a cutoff value for further analyses because of an observed transition zone at that time in the distribution of mortality and severe sepsis rates. After adjustment, patients who underwent surgery within 22 hours had a significantly lower mortality rate (1.2% vs 4.2%), lower sepsis rate (0.9% vs 4.5%), shorter hospital length of stay (8.7 vs 12.0 days), and shorter intensive care unit length of stay (1.4 vs 3.3 days). In patients who underwent surgery within 22 hours, neither mortality nor sepsis were affected significantly by the time to surgery. CONCLUSION: In the management of patients with blunt hollow viscus injury, early surgical treatment is needed. Patients with isolated blunt hollow viscus injury may have a poor outcome if they undergo abdominal surgery more than 22 hours after arrival in the emergency department.

BACKGROUND: In 2017, a novel classification for pelvic injuries was established by the World Society of Emergency Surgery (WSES). We validated its effectiveness using nationwide real-world data. The roles of associated vascular injury and open fracture in this system were also evaluated. METHODS: Patients with pelvic fractures in the National Trauma Data Bank 2015 dataset were retrospectively studied. First, the mortality rates were compared by WSES classification. Second, independent predictors of mortality were evaluated using a multivariate logistic regression model. Patients with and without associated vascular injuries and the same hemodynamic and pelvic ring stability statuses were compared. Patients with associated vascular injuries were compared to the proportion of nonsurvivors and survivors with unstable pelvic ring injuries. Third, the outcomes were compared between patients with open pelvic fracture and closed pelvic fracture in the mild, moderate and severe WSES classes. RESULTS: During the 12-month study period, 44,163 blunt pelvic fracture patients were included. The mortality rates were 1.8%, 3.8% and 10.6% for the mild, moderate and severe WSES classes, respectively (p < 0.001). MLR analysis showed that unstable pelvic ring injury did not significantly affect mortality (p = 0.549), whereas open pelvic fracture and associated vascular injury were independent predictors of mortality (odds of mortality: open pelvic fracture 1.630, p < 0.001; associated vascular injury 1.602, p < 0.001). Patients with associated vascular injuries showed that there was no significant difference in the proportion of patients with unstable pelvic ring injuries between survivors and nonsurvivors (37.2% vs. 32.7%, p = 0.323). In all three classes, patients with open pelvic fractures had significantly higher mortality rates and infection rates than patients with closed fractures (mortality rates: minor 3.5% vs. 1.8%, p = 0.009, moderate 11.2% vs. 3.3%, p < 0.001, severe 23.8% vs. 9.8%, p < 0.001; infection rates: minor 3.3% vs. 0.7%, p < 0.001, moderate 6.7% vs. 2.1%, p < 0.001, severe 7.9% vs. 2.8%, p < 0.001). CONCLUSIONS: Based on this nationwide study, the WSES guideline provides an accurate and reproducible classification of pelvic fractures. It is recommended that open/closed fractures and associated vascular injuries be evaluated as supplements of the WSES classification.

BACKGROUND: Head trauma patients may have concomitant facial fractures, which are usually underdetected by head computed tomography alone. This study aimed to identify the clinical indicators of facial fractures and to develop a risk-prediction model to guide the discriminative use of additional facial computed tomography in head trauma. METHODS: The authors retrospectively reviewed head trauma patients undergoing simultaneous head and facial computed tomography at a Level II trauma center from 2015 to 2018. Multivariate logistic regression analysis was used to evaluate independent risk factors for concomitant facial fractures in head trauma patients using data collected from 2015 to 2017, and a risk-prediction model was created accordingly. Model performance was validated with data from 2018. RESULTS: In total, 5045 blunt head trauma patients (development cohort, 3534 patients, 2015 to 2017; validation cohort, 1511 patients, 2018) were enrolled. Concomitant facial fractures occurred in 723 head trauma patients (14.3 percent). Ten clinical and head computed tomographic variables were identified as predictors, including age, male sex, falls from elevation, motorcycle collisions, Glasgow Coma Scale scores less than 14, epistaxis, tooth rupture, facial lesions, intracranial hemorrhage, and skull fracture. In the development cohort, the model showed good discrimination (area under the receiver operating characteristic curve = 0.891), calibration (Hosmer-Lemeshow C test, p = 0.691), and precision (Brier score = 0.066). In the validation cohort, the model demonstrated excellent discrimination (area under the receiver operating characteristic curve = 0.907), good calibration (Hosmer-Lemeshow C test, p = 0.652), and good precision (Brier score = 0.083). With this model, 77.1 percent of unnecessary facial computed tomography could be avoided. CONCLUSION: This model could guide the discriminative use of additional facial computed tomography to detect concomitant facial fractures in blunt head trauma. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

INTRODUCTION: The endpoint of resuscitative interventions after traumatic injury resulting in cardiopulmonary arrest varies across institutions and even among providers. The purpose of this study was to examine survival characteristics in patients suffering torso trauma with no recorded vital signs (VS) in the emergency department (ED). METHODS: The National Trauma Data Bank was analyzed from 2007 to 2015. Inclusion criteria were patients with blunt and penetrating torso trauma without VS in the ED. Patients with head injuries, transfers from other hospitals, or those with missing values were excluded. The characteristics of survivors were evaluated, and statistical analyses performed. RESULTS: A total of 24,191 torso trauma patients without VS were evaluated in the ED and 96.6% were declared dead upon arrival. There were 246 survivors (1%), and 73 (0.3%) were eventually discharged home. Of patients who responded to resuscitation (812), the survival rate was 30.3%. Injury severity score (ISS), penetrating mechanism (odds ratio [OR] 1.99), definitive chest (OR 1.59) and abdominal surgery (OR 1.49) were associated with improved survival. Discharge to home (or police custody) was associated with lower ISS (OR 0.975) and shorter ED time (OR 0.99). CONCLUSION: Over a recent nine-year period in the United States, nearly 25,000 trauma patients were treated at trauma centers despite lack of VS. Of these patients, only 73 were discharged home. A trauma center would have to attempt over one hundred resuscitations of traumatic arrests to save one patient, confirming previous reports that highlight a grave prognosis. This creates a dilemma in treatment for front line workers and physicians with resource utilization and consideration of safety of exposure, particularly in the face of COVID-19.

OBJECTIVE: Stable patients with less severe injuries are not necessarily triaged to high-level trauma centers according to current guidelines. Obese patients are prone to comorbidities and complications. We hypothesized that stable obese patients with low-energy trauma have lower mortality and fewer complications if treated at Level-I/II trauma centers. Methods: Blunt abdominal trauma (BAT) patients with systolic blood pressures ≥90mmHg, Glasgow coma scale ≥14, and respiratory rates at 10-29 were derived from the National Trauma Data Bank between 2013-2015. Per current triage guidelines, these patients are not necessarily triaged to high-level trauma centers. The relationship between obesity and mortality of stable BAT patients was analyzed. A subset analysis of patients with injury severity scores (ISS) <16 was performed with propensity score matching (PSM) to evaluate outcomes between Level-I/II and Level-III/IV trauma centers. Outcomes of obese patients were compared between Level-I/II and Level-III/IV trauma centers. Non-obese patients were analyzed as a control group using a similar PSM cohort analysis. Results: 48,043 stable BAT patients in 707 trauma centers were evaluated. Non-survivors had a significantly higher body mass index (BMI) (28.7 vs. 26.9, p < 0.001) and higher proportion of obesity (35.6% vs. 26.5%, p < 0.001) than survivors. After a PSM (1,502 obese patients: 751 in Level-I/II trauma centers and 751 in Level-III/IV trauma centers), obese patients treated in Level-I/II trauma centers had significantly lower complication rates than obese patients treated in other trauma centers (20.2% vs. 26.6%, standardized difference = 0.151). The complication rate of obese patients treated at Level-I/II trauma centers was 20.6% lower than obese patients treated at other trauma centers. Conclusion: Obesity plays a role in the mortality of stable BAT patients. Obese patients with ISS < 16 have lower complication rates at Level-I/II trauma centers compared to obese patients treated at other trauma centers. Obesity may be a consideration for triaging to Level-I/II trauma centers.

OBJECTIVE: The revised Baux score (age total body surface area (TBSA) burned and inhalation injury)) is predictive of mortality in burn patients. Our study objective was to assess whether the addition of body mass index (BMI) to the revised Baux score would be of value. We posited that increasing BMI follows a pattern similar to age and TBSA in the revised Baux score after severe burn injury. METHODS: Patient data from the burn registry was queried for patients admitted between 1/1/2013 to 8/31/2019. Patients 12 years or older with a TBSA of 20% or greater burn were included. Inpatient outcomes were analyzed based on BMI. RESULTS: 56 of 1365 patients met inclusion criteria. Mean age of the study population was 48.25 years and 64.3% of patients were male. Median BMI was 25.8 and median TBSA was 26.5. Inhalation injury was present in 44.6% (25/56) of patients. Median hospital length of stay (LOS) and ICU LOS were 21.5 and 17 days respectively. On bivariate analysis, non-survivors had higher TBSA (41.5% vs 25.5%, p = 0.034), more inhalation injury (83.3%, 10/12 vs 34.8%, 15/43 p = 0.003) and higher complication rates (91.6%, 11/12 vs 59.1 %, 25/43, p = 0.043). Survivors also had higher BMI (28.2 vs 23, p = 0.003) and increased hospital LOS (24 vs 5.5, p = 0.003). Automatic model fit in binary logistic regression showed a negative relationship between BMI and mortality. CONCLUSION: We found a negative relationship between BMI and mortality. Pre-obesity appears to have a protective role, but BMI was not found to be a useful addition to the revised Baux score. Larger sample sizes may be of benefit a for a for a more definitive understanding of the role of BMI with regards to burn survival.

Objective: The number and type of patients treated by trauma centers can vary widely because of a number of factors. There might be trauma centers with a high volume of torso GSWs that are not designated as high-level trauma centers. We proposed that, for torso gunshot wounds (GSWs), the treating hospital's trauma volume and not its trauma center level designation drives patient prognosis.Methods: The National Trauma Data Bank was queried for torso GSWs. The characteristics of torso GSWs in trauma centers with different volumes of torso GSWs were compared. The association between torso GSW volumes of trauma centers and the outcomes of torso GSWs were evaluated with propensity score matching (PSM) and multivariate logistic regression (MLR) analysis.Results: There were 618 trauma centers that treated 14,804 torso GSW patients in two years (2014-2015). In 191 level I trauma centers, 82 of them (42.9%, 82/191) treated <1 torso GSW per month. After well-balanced PSM, patients who were treated in higher volume trauma centers (≥9 torso GSWs/month) had a significantly lower mortality rate (7.9% vs. 9.7%). Patients treated in trauma centers with ≥9 torso GSWs/month had a 30.9% (odds ratio = 0.764) lower probability of death than if sent to trauma centers with <9 torso GSWs/month. Treatment in level I or II trauma centers did not significantly affect mortality.Conclusion: There is an uneven distribution of torso GSWs among trauma centers. Torso GSWs treated in trauma centers with ≥9 torso GSWs/month have significantly superior outcomes with regard to survival.

BACKGROUND: The advanced technology of interventional radiology may contribute to a rapid and timely angioembolization for hemostasis. We hypothesized that unstable hemodynamics is no longer an absolute contraindication of nonoperative management (NOM) in blunt splenic injury patients using rapid angioembolization. METHODS: From January 2009 to December 2019, blunt splenic injury patients with unstable hemodynamics [initial pulse >120 beats/min or systolic blood pressure <90 mm Hg] were included. Either emergency surgery or angioembolization was performed for hemostasis because of their unstable status. The characteristics of patients who underwent angioembolization or surgery were compared in each group (all patients, patients with hypotension, patients without response to resuscitation and hypotensive patients without response to resuscitation). RESULTS: A total of 73 patients were included in the current study. With respect to all patients, 68.5% (N = 50) of patients underwent NOM with angioembolization for hemostasis. Patients who underwent angioembolization for hemostasis had a significantly lower base deficit (5.3 ± 3.8 vs. 8.3 ± 5.2 mmol/L, p = 0.006) and a higher proportion of response to resuscitation (82.0% vs. 30.4%, p < 0.001) than did patients who underwent surgery. However, there was no significant difference in the proportion of hypotension (58.0% vs. 65.2%, p = 0.558) between these two groups. There were 44 patients with hypotension, and the angioembolization could be performed in 65.9% (N = 29) of them. Patients who underwent angioembolization had a significantly higher proportion of response to resuscitation than did patients who underwent surgery (89.7% vs. 33.3%, p < 0.001). In hypotensive patients without response to resuscitation (N = 13), 23.1% (N = 3) of the patients underwent angioembolization successfully. There was no significant difference in time to hemostasis procedure between patients who underwent angioembolization or surgery (24.7 ± 2.1 vs. 26.3 ± 16.7 min, p = 0.769). The demographics, vital signs, blood transfusion amount, injury severity, mortality rate and length of stay of patients who underwent angioembolization were not significantly different from patients who underwent surgery in each group. CONCLUSIONS: With a short preparation time of angioembolization, the NOM could be performed selectively for hemodynamically unstable patients with blunt splenic injury. The base deficit serves as an early detector of the requirement of surgical treatment.
